Hello all,

I am trying to plot streaklines over my 2-D airfoil simulation in paraView. I am able to make the streaklines appear, and I can change the length and resolution by changing the "Termination Time" and "Force Reinjection Every NSteps", however to my surprise the simulation does not change as I advance the time. Some questions:

1. Does the streakline filter always show the streakline from time = 0 to time = Termination Time, or can it be made to show e.g. always the last N timesteps, which would make videos more interesting.

2. When all else remains constant, if I change the Termination Time to a much higher number (long after the particle will have left the domain), the traces change: why is that?

3. Why does the streakline plot not change as time is advanced?

Some particulars:
- Input Source: my case data, top of Pipeline Browser
- Seed Source: a line I generated on my domain
- ParaView version: 4.1
- The case is transient (inlet airspeed direction is changing), hence the need for the streaklines to be constantly updated.

Thanks in advance for any assistance that can be offered.
